Hello,
I have initiated Bitlocker decryption of my secondary disk on Windows 11, from the Powershell, however it's been 5 days and the percentage of encryption has never gone below 99% (please see the screenshot attached). In fact, it looks like everything is stuck. Considering I have already had nightmares before, thanks to Bitlocker, I wonder why Microsoft is pushing this obnoxious software down our throats, without even giving us users a choice. Bitlocker is a piece of junky software, it creates more troubles than anything else. Complaints aside, I wonder if there is a way to interrupt the decryption process at this point, as I would like to get back to using my computer normally, without damaging my data.
Could anyone help with this? Does anyone have a good solution for this problem?
Thank you in advance.

There is no option to suspend the process unfortunately. There never was. That is why I went on with Powershell.

2022-09-29T13:26:52.27+00:00 Thanks for the suggestion. So if I write this command in Powershell, it should interrupt the decryption process without causing damage to the data?

2022-09-30T14:02:43.82+00:00 At this point I would just format the disk... What a waste of time and SSD life... Whatever. How do I know that after formatting the disk Windows won't reintroduce Bitlocker on the disk itself?

2022-10-01T00:07:48.453+00:00 Eh, can I just format the drive without suspending the decryption process? Or should I reset the PC first? Thank you in advance.

2022-10-01T16:48:33.333+00:00 Does this mean the decryption is over? I just ran it from the Terminal, over the empty disk:

2022-10-01T16:05:52.9+00:00 Thank you. I followed the guide and tried to modify the registry accordingly, however I cannot find this parameter in there at all: PreventDeviceEncryption
All I see is this:
What can I do? Create a key with that naming and set its value to 1? "PreventDeviceEncryption"
Thank you in advance.
